ABSTRACT

Objective: This study evaluated sonification and tactification for encoding urgency of system health status presented in the ground control station (GCS) visual interface of an unmanned aircraft system (UAS), and the observer’s perception of urgency.

Background: The barrage of data in the GCS visual interface has the potential to isolate the operator from detecting system hazards that threatens the ability of the operator to operate the UAS effectively.

Method: The pitch of the UAS’s engine revolutions per minute was mapped to a sonification, and excessive attitude upset of the UAS was mapped to a tactification in order to present a continuous awareness of the system’s health without being invasive and obtrusive. Participants with and without flying experience were required to monitor system health, while carrying out a secondary task.

Results: Regardless of flying experience, sonification enhanced hazard detection compared to a visual-only GCS interface, but tactification did not aid performance.

Conclusion: While multimodal displays have been studied in remotely piloted vehicles, this is the initial effort to demonstrate that sonification can influence perceived urgency leading to greater warning compliance. Further research is warranted to develop guidelines to ensure that non-visual signals can convey different levels of urgency for a continuous awareness of a system’s health, and thereby permit the operator to establish the appropriate level of priority to address the alarmed condition.

编码系统危害紧急度的多感官提示:操作员经验对感知紧急度的影响

摘要

目的:本研究评估了无声飞机系统(UAS)地面控制站(GCS)可视界面中呈现的超声和触觉编码系统健康状况的紧迫性,以及观察员的紧迫感。

背景:GCS可视界面中的数据弹幕有可能使操作员无法检测到威胁操作员有效操作UAS的系统危险。

方法:将UAS引擎每分钟转数的螺距映射为声波,将UAS过度的姿态不正常映射为tactification,以呈现对系统健康的持续了解,而不会受到侵扰和干扰。具有和没有飞行经验的参与者都需要在执行次要任务时监视系统的运行状况。

结果:不论飞行经验如何,与仅使用视觉的GCS界面相比,超声处理都增强了危险检测的能力,但触觉处理对性能没有帮助。

结论:虽然已经在远程驾驶车辆中研究了多模式显示,但这是证明超声作用可以影响感知的紧急性并导致更大的警告依从性的初步努力。有必要进行进一步的研究来制定准则,以确保非视觉信号可以传达不同级别的紧急情况,以不断了解系统的健康状况,从而使操作员可以建立适当的优先级来解决警报状况。
